opposite sideof the upper end of plate DI by the same bolts `which secure the rea-fr iendof-` 65 y 4itsupper end journaled in the bearing T, yand fr the brace-arm to the said plate D', and extending downward-and outward from the said plate M is an arm, N', the lower end of which has a vertical bearing for the lower portion of the vertical standard U of thegfurrow-wheel W. The rear end of the plow-beam is pivotally connected to the lower end of plate D by a single bolt, and thereby the front end of the said plow-beam is adapted to be raised or lowered.

O represents a bearingblock, which is secured on the plow-beam ata suitable distance from the front end thereof, and in the said bearing-block is journaled the upper end of the standard P', to the lower end of which is journaled a revolving colter, B'. A

S' represents a lever, whichis 'pivoted on a shaft on the upper side of a cross-bar, T', that connects the arm O with the bar E, and is arranged parallel with and ata suitable distance in rear of the cross-bar B. On the shaft directly over the plow-beam is alever, S5, which is connected to the plow-beam by means of a link, U. The function ofthe said lever is to raise or lower the frontend of the plow-beam, and the said lever S' is provided with devices similar to those previously described in connection with the lever O, whereby said lever S may be secured at any desired angle.

V represents a supporting-bar, which is secured to the cross-arm T and has its rear end npturned and adapted to support the seat X for the driver.

Y represents a pair of arms, which have their Vfront ends pivoted to one end ofthe shaft F on opposite sides of the wheel I. The rear ends of the said arms are connected by acrossbar, Z', on which is secured a bearing-block, A2. To the front end of the inner arm Y is secured a bearing-block, B2, which projects from the inner side of said arm, and in the said bearing-blocks A2 and B2, is journaled a longitudinal shaft, C2, which has a pinion, D2, that meshes with the wheel I. To the rear end of said shaft is secured a sprocket-wheel, E2. vFrom the outer arm Y', near the rear end thereof, depends a pair of standards or hangers, F2, which are strengthened by suitable braces, G2, and to the lower ends ofsaid hangers are secured bearing-boxes H2, which are adapted to move laterally and in which is journaled alongitudinal shaft, l2. To the extreme rear end of the shaft I2 is secured a circular hubdisk, K2, to which is secured a series of radial curved knives or cutters, L2. The said disk and its knives or cutters constitute a pulverizer, the operation of which will be described hereinafter. Immediately in front of the disk K2, and rigidly secured to the shaft I2, is a sprocket-wheel, M2, which is smaller than the wheel E2 and is connected thereto byl an endless chain, N2. Y

O2 represents a bell-crank lever, which is pivoted to the bar E at a suitable distance from `the same on a bolt, Y2.

arms Y' and the devices attached thereto constitute a swingingframe, which carries the pulverizer and the connections between the same and the drivingshaft, and the function of the hand-lever O2 is to raise or lower the rear end of the said frame, and thereby raise orlower the rear end of the pulverizer. The lever O2 has 'a segment-plate, B2, which is secured to thev bar E and bears against the side of the lever, and to the latter is secured a vspring-actuated bolt, S2,of the usual construction, which is adapted to engage either of a series of openings or notches iny the segmentplate,so as to secure the lever,and thereby secure the frame, at any desired position.

T2 represents a plow, which comprises a mold'-board,U2,having a shear or cutting edge,

V2, and is provided with a point, W2, the usual landside and soleplate being dispensed with.

X2 represents the plow-standard, which is bolted to the'landside-edge of the mold-board and has its upper end inserted between the bars C of plow-beam B', and pivoted between A series of openings, Z2, aremade through the'plow-beam for the reception of the bolt Y2, so that the standard may be secured to the plow-beam at any desired distance from the front end thereof.

A3 represents a brace-arm, which has itsv lower end pivoted to the plowshare, as shown, and has its upper end arranged between the bars C of the plow-beam and provided with a series of openings, B3, adapted to register with openings D3 in the plow-beam. A bolt, E, passes through the openings in the plow-beam and through one of the openings in the adjusting brace-arm, so as to secure the latter at any desired angle, and thereby secure the plowshare at any desired angle with relation to the ground, sothat the plow will be drawn into and held in the ground. Y

It is obvious that by dispensing with the landside and sole-plates the friction on the landside of the plow and on the bottom thereof is entirely obviated, and consequently the draft of the plow is very materially reduced.

In order to prevent the front end of the plowbeam from vibrating laterally, We provide a standard, F, which is provided at its upper end with a Thead, G3,that is bolted to the under side of the front bar, B, of the frame. This standard extends down betweenthe bars C' of which the plow-beam is composed, so that the plow-beam is free to be moved vertically on the standard. The lower end of the standard is prevented from vibrating laterally by means of a. brace-rod, H2', which has its ends bolted to the under side of the cross-bar B at the ends thereof, and has its central portion secured to the lower end of standard F,as shown in Fig. 5. The said standard F3 and brace-rod Ha also serve as a truss, which very materiallystrengthens the frame.

The operation of our invention is as follows:

IOO

IIO

When plowing, the front end of the plow-beam sired angle and caused to run at the desired depth into the ground by hitching the whiiiietree at the proper heightinto the clevis on the frontend of plow-beam. The pointand cuttingedge of the-plowshare retain thesame position to the ground at any depth,because the fu rrowwheel W follows in' thefurrow, which lowers r therear end of the frame in'proportion to the depth lof the furrow plowed. The'forward motion of the plow causes the traction-wheel H to rotate by contact with the earth, and thereby rotate the shaft F, to which it Ais secured. "This imparts 'rot-ary motion to the gear-wheel I, which is in turnimparted to the shaft G2, the latter revolvi'ngata higher rate of speed than the shaft F, for the reason that the pinion D2 is much smaller than the wheel.

I. The rotary motion of the shaft C2 is communicated to the shaftwhich carries the pulverizer by reason of the sprocket-wheels and endless chain, previously described,and,`iuas much as the sprocket-wheelonthe p'ulverizer- :shaft is smaller than the sprocket wheel on the shaft C2, the pulverizer is rotated at considerable speed. The pulverizer is located, as will be observed byreference to Figs. 1 and 2,.on

-the furrow side of theplowshare to the rear "and right-hand sidey just Vfar enough to allow the furrow to be turned over in front `ofthe verizer, the pulverizer-rame is supported in an elevated position, and the pinion D2 is slipped rearward on the shaft C, so as to kbe out of engagement with the gear-wheel I. Said pinion DIl is provided with aset-screw, as shown in Fig. 1, by means of which the pinion may Vbe secured to the shaft at any desired point,

either when engaged with the gear-wheel I. l

By having the whifetree connected to the front end -of the plow-beam and not to the tongue the draft isexerted directly `on the plowshare, andconsequently theframeis relieved of the strain. VThe colter in advance or disengaged from n of the plow operates in the usual manner.

It will be understood that the frame and the wheel H resist the side strain that is on the mold-board plow, thereby obviating the -use of a landside, and the casterwheelWobviatcs the use of a heel or sole to the plow.

Having thus described our invention, we claim-.- f
